Title: Hydraulic elevator control panel
Inventor: HAYASHI TAKASHI
IPC: B66B7/00
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To easily connect a newly-established control panel on an established hydraulic power unit by providing a connecting part with the newly-established control panel and a fixing hardware holding and fixing a frame of the hydraulic power unit on the upper part of mounting spacer arranged between the newly-established control panel and the established hydraulic power unit and the lower part, respectively. SOLUTION: Between a newly-established control panel 4 and an established hydraulic power unit 1, mounting spacer 5a is arranged. On the upper part of this mounting spacer 5a, a connecting part such as a connecting hole with the newly-established control panel 4 is formed. On the lower part of the mounting spacer 5a, a connecting means by a fixing hardware 6 holding a frame 2 of the established hydraulic power unit 1 is constituted. Therefore, because a connecting hole is not required to be worked at a location coinciding with the connecting hole of the newly-established control panel 4 on the frame 2 of the established hydraulic power unit 1 at an actual place, generation of metallic powder within a machine chamber is eliminated.  Therefore, curing and cleaning of equipment become unnecessary, and the connection of the newly-established control panel 4 and the established hydraulic power unit 1 can be easily performed.

Title: Automatic control method of air pressure
Inventor: MORIYA KAZUO
IPC: G05D16/00
Filed: 1983-07-18
Abstract: PURPOSE:To ensure the air pressure control with high precision without receiving the effect of variance of the original pressure, by controlling an air regulator at the side of a pressure acting element to give a rough control to the air pressure and controlling an air regulator at the air supply side to give a fine control of air pressure respectively. CONSTITUTION:At the outset, the set air pressure PS and a rough control area PS+ or -DELTAP are set by a setter 33. A plus pulse is delivered to a rough control motor M2 if the air pressure PX is smaller than PS-DELTAP. Thus the pressure of a control spring 22 is increased. Then the pressure PX of a regulator R2 rises up to a level equal to the pressure of the spring 22. When the PX rises up gradually to exceed the area PS-DELTAP, the pulse feed is stopped to the motor M2. Thus a rough control is through. Then the pressure PX is compared with the set air pressure PS. Then a plus pulse is supplied to a motor M1 when the PX is smaller than the PS. Thus the spring pressure of an air regulator R2 is increased. When the PX rises up gradually to a level equal to the PS, the pulse feed is stopped to the motor M1.

Title: Distance measuring apparatus
Inventor: UENO YASUSHI
IPC: G01S17/931
Filed: 1991-06-03
Abstract: PURPOSE:To ensure the detection of the distance to a close preceding target which is running at the side and the distance to a preceding target which is moving in the faraway distance requiring detection. CONSTITUTION:A cylindrical lens 20 is arranged at a light sending part 10 so that the lens can be moved along an optical axis. An emission expanding angle theta of laser light beam is adjusted by moving the lens. The light casting range is determined based on the emission expanding angle and the arriving distance. When the expanding angle is made large, the arriving distance becomes short. When the expanding angle is made small, the arriving distance becomes long. After the output power of the laser light is determined based on a vehicle speed sensor 31, the expanding angle is changed from the large state to the small state based on the output power. The casting range is scanned from the near part to the faraway part. Thus, the vehicles located from the near part to the faraway part can be positively detected.

Abstract: PURPOSE:To rise reliability by providing a coupling electrode detecting a micro partial discharge within a compressed gas insulation switching device at the outside thereof and by pulling out an electromagnetic wave signal due to the micro partial discharge via a coupling insulator provided at a flange of a tank to the outside thereof. CONSTITUTION:When within a compressed gas insulation switching device(GIS), e.g. a foreign material of a metal wire exists and a partial discharge is generated therefrom, an electromagnetic wave due to that propagates in the GIS via a high voltage conductor 1, passes through an opening 5 of a flange 4, and through a transmissible insulator 7 too and arrives at a coupling electrode 20. In brief, this results in that the electromagnetic wave within the GIS is pulled out to the outside of the GIS. The electromagnetic wave at the coupling electrode 20 is transmitted to high frequency electromagnetic wave measurement equipments such as a preamplifier, a spectrum analyzer and the like via a matching resistor 26 having a good transmission characteristic and high frequency coaxial cables 27, 14. Thereby, the inside micro partial discharge can be detected with good accuracy without generating gas leak.

When an excessive pressure difference is applied, a sealing diaphragm 102a is pushed onto a wavy face 110a so that the diaphragm is prevented from being broken. In addition, the movement of the enclosed liquid 103a to the face is absorbed by the elastically deformed diaphragm 111  so that the pressure sensor 104 may be prevented from a destruction. In the absence  of the excessive pressure difference, the diaphragm is restored to the original position. In case of an opposed pressue difference, a diaphragm 102b comes in contacg  with a wavy face 110b.
